4.1 SEX-Dose sex differ will have influence on student’s score? From the histogram graphs above, we can confirm that mean in four subjects are trend to normally distributed. To test whether the mean for reading, writing, math and science is the same for males and females, an independent samples t-test tool is suitable because it can compare the means of a normally distributed interval dependent variable for two independent groups. H0: Females have no significant difference and high mean score than males in reading score H1:
In “Cooling Down Our Brain,” Jason Peters talked about how researchers proved that self-control can be developed by specific mental exercises. He explained an experiment named “the marshmallow test” and how the result of the experiment showed that children who had self-control became more successful in their lives than those who did not have it. The author further stated that additional research showed that the human brain has “hot” and “cool” areas and everyone can train the “cool” part to control the impulses.
The Stroop Effect and the Horse Race Model Phenomena Rochelle Hall City University of New York- Brooklyn College Abstract Introduction The Stroop test phenomena was first introduced to the world of Experimental Psychology by J.R. Stroop in the year 1935. This landmark article has since influenced the research and publication of over 700 other Stroop-related articles. MacLeod (1991, p. 163).
The other being how perceptions of other races change after having or not having an interracial room during the first year of college. The study was a natural field experiment. Whereas in a lab, conducting field research allowed to follow long term interactions. There was no need for manipulation and random assignment was guaranteed by how the school assigned housing to freshmen, which served as the independent variable.
Many people underestimate the ability of the mind. Some do not fully realize that we all have a brain, but it is the experiences that a person has that make up the mind. With such experiences, the mind has the capability to recall and judge. Due to such dynamics, the mind should be considered as a crucial attribute in the daily lives of us humans as it can either daunt us or help us. However, the mind can be controlled to a certain extent.
In 1879, when Pratt started to experiment with the Natives to which started teaching them English and Christianity as well as employment trades, not just the change of language or the practice of a religion without their consent, but they were actually being trade for employment to work as a young age, and not just that but Pratt stated or referred to them as objects not humans. Which is really inhumane by stating that he was actually “fixing them” like if there was something wrong with them and they needed fixing, treating them like things like you were to fix your car, or computer. “Not so surprisingly, the inmates overwhelmingly chose conversion and assimilation to longer imprisonment, so Pratt saw his experiment as a success and published
Society and government require people to be obedient towards authority, but is it always the best thing to do? During the aftermath of World War II many of the major leaders of the Nazi regime were put on trial for crimes against humanity (History.com). These trials were known as the Nuremburg war trials, were most of the convicted proclaimed that they were “just following orders” (McLeod 584). Being an accomplice to a crime is also against the law. In the Nuremburg trials, those accused were not breaking the law that their government had created, they were actually following it.
The Zimbardo experiment was one that overseer even saw that it was unethical after coming to his senses. He put an ad in the newspaper for college students to submit for the experiment, where twenty-four would be chosen. The students would be paid fifteen dollars per day for two weeks of the experiment. However, it did not even last one week. It was an attempt of “good triumphs” in a negative environment, which did not work within the students’ roles.
The Milgram experiment and the society Speaking of one of the most renowned psychological experiment, which even replications on TV are done, is the Milgram experiment, on obedience to authority figures. It involves the measurement of how much participants will to obey the authority, in order to explain the reason why soldiers obeyed to allow the Holocaust, the homicides of millions of Jews, happened. With the participants’ roles as a teacher to punish a learner by incrementing degrees of electric shocks, though they didn’t know it’s staged, 65% of them did it to the last under the horrendous moans and the commands of the experimenters, which surpassed the expectation of 1.2%. Milgram himself elaborated two theories, encompassing theory of
Then the Skinner box will be discussed, finally leading to the studies of Loftus and Palmer on the link between language and memory. The role and importance of ecological validity in each body of research will be discussed and evaluated. Ecological validity is how much the
Eventually, the researchers cooperated a control group in their study. The control group consisted of the men that were previously involved in the study last winter. The researcher selected two hundred of the men that were between certain ages and examine them. Also, this group of men did not have syphilis. Although, some of the men had to be turned down because their test result were positive for syphilis.
I believe this experiment started when my professor planted this "un-occupied, un-employed" thought in my head. In this pre-experiment phase, I had a blind vision. We as students are trained to hypostasize before an experiment but as much as I wanted to predict what was going to
Harold Urey - Experiment Harold Urey’s discovery of deuterium is perhaps his most revolutionary discovery. Not only did Urey receive a Nobel Prize for his work towards hydrogen-2, deuterium would go on to become invaluable both to chemists’ understanding of the elements, and the field of chemistry as a whole. Urey’s pursuit of deuterium began in 1931, after his interest was piqued by a scientific journal that discussed the supposed existence of the isotope. Using the Balmer series, which is the series of lines in the hydrogen atomic emission spectrum, Urey and a colleague by the name of George Murphy, calculated where hydrogen-2’s emission lines should be located. They determined that the isotope’s emission lines would be “redshifted” (shifted
The Little Albert experiment was a case study showing empirical evidence of classical conditioning in humans. The study also provides an example of stimulus generalization. It was carried out by John B. Watson and his graduate student, Rosalie Rayner, at Johns Hopkins University. The results were first published in the February 1920 issue of the Journal of Experimental Psychology. After observing children in the field, Watson hypothesized that the fearful response of children to loud noises is an innate unconditioned response.
For those who agreed, release forms were signed and the experiment began. Participants completed a questionnaire that assessed demographic information (i.e., age, gender, and relationship status), drug use, and the attractiveness of other bar patrons from their preferred sex. Attractiveness
